Should i make a duct tape boat?

so i was searching the web for a reasonable dinghy to have to use once in a while to go fishing and what not or just to ride around in. but im not a man of money. i figured it would be cheaper to buy around 20 rolls of duct tape and some wood. if i constructed a wooden boat frame and used duct tape to cover it as a hull, would this be practical? would it last a while or fall apart after a use or 2? and also for a 2 person dinghy that is that is about 4' wide at the top,5' long, and 3' tall, would i need that much duct tape? thanks yallz!
